Number of Pit Bulls in the US

The main idea is that there are no accurate statistics kept on the total number of Pit Bulls in the United States of America. Anyway, the main idea is that Pit Bulls represent 5% of the total dog population in the United States. Are Pit Bulls aggressive? Studies show that in a 10-year span, from 1966 â€“ 1975, there is only one documented case of a fatal dog attack in the United States by a dog which could even remotely be identified as a â€œPit bullâ€.
